Hydraulic systems and components supplier Hytec Group announced last month that it has increased its distribution and support for the full range of Bosch Rexroth oil control cartridge valves throughout sub-Saharan Africa as part of a new joint venture into Africa.
This expanded support will enhance Hytec’s logistics, sales and support capabilities of the products, and includes a more competitive pricing structure for this series.
The valve range simplifies conventional compact hydraulic systems and enhances hydraulic circuits where space and weight present fundamental application constraints. Bosch Rexroth cartridge valves are characterised by a long service life. At an operating pressure of 350 bar, the cartridge solenoid valves are rated for a product life of ten-million cycles.
The unique design of the cartridge valves reduces the amount of interconnecting pipework required within the hydraulic circuit through a customised manifold. This reduces the overall weight and space requirements of the machine, resulting in decreased power requirements, contributing to improved energy efficiency.
Interconnections of piping within a conventional hydraulic system are a common source of fluid leakage. The compact design and reduced piping requirements of the Bosch Rexroth cartridge valves, therefore, reduce inspection and maintenance requirements, facilitating a more efficient hydraulic operation.
The valves offer a typical working pressure of 350 bar, with some rated to 630 bar. Bosch Rexroth cartridge valves have flow rates of up to 700 ℓ/min for fluids between –30 °C and 100 °C.
The screw-in cartridge valve range includes pressure control valves, check valves, counterbalance valves, flow control valves, logic elements, directional valves and proportional valves.
